Far Away and Long Ago
"A stellar explosion has smashed the record for most distant object in the known universe.
The gamma-ray burst came from about 13 billion light-years away, and represents a relic from when the universe was just 630 million years old.
"It easily surpassed the most distant galaxies and quasars," said Edo Berger, an astrophysicist at Harvard University and a leading member of the team that first demonstrated the burst's origin. "In fact, it showed that we can use these spectacular events to pinpoint the first generation of stars and galaxies."
